English Amiga Board - View Single Post - Choosing a new ATX power supply for an expanded Amiga 4000

Hello,
i have a quite expanded Amiga 4000, i noticed that i have a lot of troubles with the SCSI chain with unexpected hung ups and resets. The chain is properly terminated with active terminators so it's not the problem, if I unplug some devices it seems to be working better, so I'm thinking to buy a new, high quality, power supply, now I have an unbranded ATX one with 400 WATT power, quite old.

this is my configuration:

- Amiga 4000 Desktop 64MB ram in full tower
- CSPPC 200Mhz e 68060, 66MHz, 128mb RAM
- Mediator A4000D
- Picasso IV
- Delfina Lite
- Ati Radeon 9200 128MB
- Voodoo 3 16mb
- Ethernet PCI
- 2x Hard Disk SCSI UW 15k rpm
- SSD Ata on a ACARD SCSI3=>SATA adapter
- Iomega Zip100 SCSI
- Iomega JAZ 2GB
- DVD-ROM SCSI2
- Cd-Burner 6x4x16 SCSI2
- CF IDE Adapter

what power is supposed to be enough for such a configuration?
I was thinking about 500Watt but with so much devices and expansion maybe it could be underpowered.
